Instead of haring the :g 23 slidahle in the here of the cylinder l5, l provide a shell 24 of oonipaiatirely thin inet-al that is readily slidable in tlie cylinder 15, and the head ou the stein is Jorined of asize to lit slidahly in the shell 2l. The end Aof the shell adjacent the plunger stein 17 is closed by a screw disk or cap 25 haring a number of apertures therein, as indicated in Fig. fl. This cap is removed to till the shell .with the plug 23, when the head Q2 is at the inner end portion of the shell as indicated in Fig. l, and the plug will engage the nap lien returned to the shell. lt will thus he Seen troni Fig. l that the plug iteeli doei niet slide in the bore of the cylinder, huttlie eliell will nieve hack and forth in the cylinilei and the liead 22 of the valve stern engag ing the plug in the. shell, will canse the valve eteni to he advanced when the plum ger is screwed inwardly to open tlie valve against the pressure ofthe coil spring; while when the plunger is screwed outwardly. the Valve will close, and the head on tlie stein u cylinder to follow the plunger until the v'alto is seated.

llfhen the temperature et the easing or the cylinder becomes' suiiiciently elevated to lique'iy the plug, if the valve is in the open position as shown in Fig. l, the 'tension of or other fluid flowingI through it lro the coil spring will exert a pressure on the head 22, Causing it to force the now fluid contents of the shell outwardly through the apertures in the end 25 ot' the shell, as indicated in l'ig. t2. And this niov'em-` t et the valve stein will cause the valve to hecoine seated, e'iiectually preventing any fur.- ther ontilow from the tanlr.

The easing is also arranged to operate as a strainer or separator 'for the fi'asolene m the auch al por tank 10, which is etfeoted by causi' iluid to he r-:ithdrawn frein the een tion of the casing, and by arranging the inlet tube 19 at the upper portion ot the easing. ,its Sliowii I provide an outlet pipe QG in the casing Whose open end or mouth E27 is located at the intermediate or central portion el the casing; thin tube connecting tieve with an outlet pipe Q8. As 'the .fluid tlirou nli the inlet pipe into the will ill the casing, and the lie-:wier suoli as water iil .tall to the bottom ot the easing by grav'ity, and dirt or part' will also he precipitated to the lo"- o't the easing; while the gaeoleiie er o fluid of lighter speoii'ie gravity will reni n in the upper portion of the easing and pass out therefrom Athrough the tube From time to time the val 9 at the bottoni of the easing can be opened, and the Water. and sediment drawn off through the exit roiwhich operation the inlet valve 12 can pref eraoly he previously Closed.

Haring thun` described/my invention, what l claim is:

l. 'lflie combination of a casing, a-n inlet 70 ping toward the inlet valve, a Stein on said valve-prorided 'with ahead. and a. spring 'ai said stein arranged to more the valve to rial tion and to prese the head against Jing, udnfi'ehy when the plug and plun- :he plug will permit ire petitioned to lu the nielt ing of' 'valve to close tiicinlet. The ceiiihiiiation of a casing, an inlet at one eide o'i the easing. a. Valve arranged 90 to einer: the inlet, a egf'liiider projecting from tiie Casing opg: non-metallic material oi" comparatively low melting point that is slidable in the cylinder, a p `o the out/er portion and provided with continlling means projecing from the cylinder at its outer end and arranged to advance the plug toward the inlet valve, stem on Said valine prorided with a head, and a 10a spring on Said stein arranged to more the mire te closed position and to prese the,., head against said plug, whereby when the` para; and plunger are positioned 'to lioldf.; the ralre in open posit-ion, the melting ofA the plug will permit the spring to advance the head and force the material of the .plug through the perforated plunger, and also cause the valve to cloee the inlet.

at one side oi the Casing, Valve arranged to close the inlet, a cylinder projeetiligfrom 'the casino opposite the Said inlet, a plug 0f a mater i! of comparatively low. melting point that is slida'ole in the cylinder, a 115 iger in the cylinder at tliefouter portion r provided with controlling means projecthig 'from the eyliiiler at ite outer enc and arranged to aiflvanoe thefplug toward4 tl' led with a. head., and a spring on Said Stem arranged to move the valve to closed position and to prees the head against said plug, whereby 'when the plug and plunger are positioned to hold the valve in open posil tion, the melting et the plug will permit the spring to adrance the' head and cause the valve to close the inlet.

e. The combination of a casing, an inlet at one side of the easing, a valve arranged to slidable in the 75 the valve in open g5 the said inlet, a plug of rated plunger in the cylinder at 95 a. The runihination of a casing, an inlet 110 1 inlet valve, a Stein or.. said valve pro- 120 close the inlet, a cylinder projecting from the casing opposite the inlet, a shell slidable inv said cylinder, the outer closed end of the cylinder to engage said shell, a stem on said valve projecting into' said Shell and slidable in the shell, said shell l with a non-metallic material of comparatively low melting point, the end of the shell engaged by said plunger being perforated, and :i 'spring in the casing engaging said stein to advance it and the shell to engage said plunger, whereby when the. plunger is advanced to'shift the shell and stem tohold the valve in open position with' said sprin under tension, the melting of the materia in the shell will result in the spring advancing the head to force the said 'material through the perforated end of the-Shell and close' the inlet valve.

5. Tlie'coiiibina.ion of a casing, an inlet at one side of the casing, a valve arranged to close the inlet, a. cylinder projecting from Y* the casing opposite the inlet, a shell slidable shell in said cvlinder, cap

closing the outer end oi; the cylinder and having a threaded bore, a threaded plunger operating -in said bore and engaging .one end of said shell, said end being apertured, a stem on said valve projecting .into said shell and carryi ing a head slidable in the shell',said shell being lled with a non-meta`l1ie material of comparatively low melting point, a.nd 4' spring in the casing engaging Said Stem t0 advance it and the shell plunger, whereby when the vanced to shift the shell and stem to hold the valve in open position with said spring under tension, the meltin of the material in the shell will result in t e spring advanc-v ing the head to force the -said material through the apertured end of the shell and close the inlet valve.

6. The combination of a casing, for the casing, a valve arranged the inlet and provided with a stein, connected with said stem to close the valve when free to move, a plug of a material of comparatively low melting point connected with the valve stem to normally hold the an inlet a plunger projecting into' Vmaterial the shell Will resul to engage said.

plunger is ad fwhen the valve in open position with the spring under tension, and arranged to be di melted by heat to thereby permit the spring to close the valve, and a controlling member connected with the plug to shift its position and thereby move position at will.
